What is normal blood pressure? Your comprehensive guide
ca. 19 Minuten
Are you wondering, “What is normal blood pressure?” and hoping for an answer you can understand without a medical degree? Sure, the ideal reading is often 120/80 mmHg, but that number isn’t set in stone. Your age, lifestyle, and even your genes all play an important role and can influence this reading.
Your compass for healthy blood pressure
Think of your circulatory system as the plumbing in a house. Blood pressure is the pressure in the pipes that ensures water - in your case, oxygen and nutrients - reaches even the most remote corners. But if this pressure is constantly too high or too low, the whole system will eventually suffer damage. That’s exactly why it’s so important to know and understand your readings.
This guide will walk you through it. We’ll start with the basics, show you the right measuring technique, and explain which factors you can influence yourself. You’ll learn not only what the two numbers on the display mean, but also how you can take an active role in your heart health. Being mindful of your body is the best key to long-term well-being.
Why knowing your blood pressure is so important
Healthy blood pressure is one of the most important measures of your overall fitness. If your readings are out of range, this can be an early warning sign of problems that might otherwise go unnoticed for a long time.
Here are a few good reasons to keep an eye on your readings:
- Recognize risks early: Persistently high blood pressure puts a lot of strain on your heart and blood vessels. It can significantly increase your risk of serious illnesses.
- Motivation for a healthier everyday life: Knowing your readings can be a huge motivation to make a change. Nutrition and exercise are key levers here. If you need inspiration, take a look at our 10 tips for a healthy lifestyle.
- Understand your body better: Knowing your readings helps you better assess how your body responds to stress, certain foods, or exercise.
Your blood pressure is about much more than just a number. It’s direct feedback from your body about your health. Take this feedback seriously - it’s your personal compass.

Understanding the two numbers on the monitor
When you measure your blood pressure, the device always shows two readings, usually separated by a slash, for example, 120/80 mmHg. But what do they actually mean? Think of your heart as a powerful pump that keeps your blood circulating. Each of these numbers describes a specific phase of this pumping process.
The first, always higher number is your systolic blood pressure. This reading indicates the maximum pressure in your arteries, at the precise moment your heart contracts and pumps oxygen-rich blood through your body. You can think of it as the powerful surge created when you turn a garden hose on full blast: it’s the moment of greatest strain on the system.
Systolic and diastolic readings explained
The second, lower number is your diastolic blood pressure. It describes the residual pressure in your blood vessels while your heart relaxes to fill with blood again. To stick with our analogy, it’s the baseline pressure left in the hose even when you’ve just turned off the faucet.
Only together do the two readings give a complete picture of your cardiovascular health. Persistently high systolic pressure means your blood vessel walls are constantly under enormous strain. A diastolic reading that’s too high, on the other hand, is a clear sign that your blood vessels can no longer relax properly, even when you’re at rest.
Normal blood pressure is no coincidence; it’s the result of a finely tuned interplay. Systolic and diastolic pressure are like two dancers: they need to stay in step to keep your cardiovascular system healthy and working well.
Which blood pressure readings are considered normal?
Normal blood pressure in adults is below 140/90 mmHg (IQWiG, 2024). Doctors diagnose high blood pressure, medically known as hypertension, when a reading taken in a doctor’s office is 140/90 mmHg or higher (German Hypertension League, accessed 2026).
The German Hypertension League divides the range below this more precisely, from optimal (below 120/80 mmHg) to high-normal (German Hypertension League, accessed 2026); the full classification is shown in the table in the next chapter.
What is normal blood pressure at different ages?
The same limits apply to all adults: A reading measured at the doctor's office is considered normal if it is below 140/90 mmHg (IQWiG, 2024; German Hypertension League, accessed 2026). There is no separate normal range by age, even though blood pressure rises somewhat with age in most people (IQWiG, 2024).
As an example of changes in older age, the German Hypertension League notes that blood vessels lose elasticity and the walls of the arteries become increasingly stiff (German Hypertension League, accessed 2026). Think of them like rubber bands that become a little more brittle and stiff over the years. But the fact that a reading becomes more common with age does not make it normal: In the Robert Koch Institute's Study on Adult Health in Germany (DEGS1), conducted from 2008 to 2011, almost 75 percent of people aged 70 to 79 had hypertension, including those receiving treatment (RKI, Neuhauser et al., 2013). The threshold does not change as a result.
Blood pressure table: what readings are considered normal?
For adults, a reading taken at the doctor's office is considered normal if it is below 140/90 mmHg. From 140/90 mmHg onward, the German Hypertension League distinguishes three grades of hypertension (German Hypertension League, accessed 2026). A reading of 138/86 mmHg falls into the “high-normal” category, which the league describes as “too high, but still acceptable” (German Hypertension League, accessed 2026).
| Classification | systolic (mmHg) | diastolic (mmHg) |
|---|---|---|
| optimal | below 120 (German Hypertension League, accessed 2026) | and below 80 (German Hypertension League, accessed 2026) |
| normal | 120–129 (German Hypertension League, accessed 2026) | and/or 80–84 (German Hypertension League, accessed 2026) |
| high-normal | 130–139 (German Hypertension League, accessed 2026) | and/or 85–89 (German Hypertension League, accessed 2026) |
| Grade 1 hypertension | 140–159 (German Hypertension League, accessed 2026) | and/or 90–99 (German Hypertension League, accessed 2026) |
| Grade 2 hypertension | 160–179 (German Hypertension League, accessed 2026) | and 100–109 (German Hypertension League, accessed 2026) |
| Grade 3 hypertension | even higher readings | even higher readings |
The table shows readings taken at the doctor's office and applies to adults of all ages. The 140/90 mmHg threshold refers to the average of measurements taken on two days; for home measurements, the threshold is 135/85 mmHg, measured over seven consecutive days (German Hypertension League, accessed 2026).
What is normal blood pressure at 60 or 70?
At 60 or 70, the same limits apply as at 30: A normal reading for adults is below 140/90 mmHg (IQWiG, 2024). A reading of 150/90 mmHg at the doctor's office counts as grade 1 hypertension at 70, just as it does at 40 (German Hypertension League, accessed 2026).
What changes with age is the treatment, not the classification. Depending on a person's health, doctors may be more lenient with older adults and generally do not aim for a systolic reading below 120 mmHg, because lowering it too quickly and too far can cause dizziness and, consequently, falls (German Hypertension League, accessed 2026). This is a treatment goal, not an age-based norm. According to the German Hypertension League, chronological age alone says little about how fit or frail a person is (German Hypertension League, accessed 2026). Only a measurement can show where you stand: the German Hypertension League recommends checking your blood pressure regularly, especially from age 40 onward (German Hypertension League, accessed 2026).
Is 110 over 70 a good blood pressure?
Yes: According to the German Hypertension League's classification, 110 over 70 mmHg is optimal because both figures are below 120/80 mmHg (German Hypertension League, accessed 2026). This classification applies to all adults. If you're being treated for high blood pressure at an older age, discuss your target reading with your doctor.
The next two questions answer when a reading is considered too low.
Is a blood pressure of 90 over 60 too low?
MedlinePlus, the health portal of the U.S. National Library of Medicine, defines blood pressure as low at 90 over 60 mmHg or below (MedlinePlus, 2019). A reading of 90 over 60 is therefore right at the threshold (MedlinePlus, 2019).
That doesn't automatically make it concerning. Some people consistently have low readings without symptoms, and for them these readings are normal (MedlinePlus, 2019). According to MedlinePlus, low blood pressure is only a problem if it causes symptoms such as dizziness or fainting (MedlinePlus, 2019). Some people may experience these symptoms if they stand up too quickly (MedlinePlus, 2019). If you experience symptoms like these, have a doctor check them.
What does a blood pressure of 80 over 50 mean?
A blood pressure of 80 over 50 mmHg is below the 90/60 mmHg threshold at which MedlinePlus defines blood pressure as low (MedlinePlus, 2019). If you also experience dizziness or fainting, have a doctor check the reading.
According to MedlinePlus, whether a low reading is a problem depends on symptoms, not the number alone (MedlinePlus, 2019). However, the German Hypertension League explicitly does not consider blood pressure that is too low to be healthy in older adults (German Hypertension League, accessed 2026). So if you're older and get readings like these, mention them to your doctor's office even if you have no symptoms.
Small but significant differences between the sexes
Age isn't the only factor; sex also plays a role. At younger ages, men tend to have slightly higher blood pressure than women.
Interestingly, this trend often reverses after menopause. Hormonal changes can then cause women's blood pressure to rise and even exceed men's.
So your blood pressure isn’t a static number, but the result of a complex interplay between age, sex, genetics, and lifestyle. That’s why assessing your readings always requires looking at the bigger picture.
This knowledge helps you assess your readings realistically and avoid panicking when the numbers don’t match the textbook ideal of 120/80 mmHg. It’s much more important to spot trends and understand when it’s time to take a closer look.
Don’t forget: your genetic makeup also has a major influence on how your body changes over time. Learn more about how your genes affect healthy aging in our article about the Longevity DNA Test.
Factors that influence your blood pressure every day
The question “What is normal blood pressure?” has a simple answer, but the reality is more complex. Your blood pressure isn’t a fixed value set in stone - think of it more like a dynamic speedometer for your body. It responds to countless influences, from the meal you’re eating to the thoughts running through your mind.
These fluctuations throughout the day are completely normal. But it’s important to understand which factors you can control. Your lifestyle, diet, and even your emotions are powerful tools for positively influencing your readings and strengthening your heart health over the long term.
The role of diet and exercise
What you put on your plate has a direct effect on the pressure in your arteries. Two minerals in particular play a major role here, acting as natural counterparts: salt (sodium) and potassium.
- Salt as a driver: Too much sodium acts like a water magnet in the body. This extra fluid volume increases the pressure in the blood vessels - and blood pressure rises. The tricky part is often the hidden salt in processed foods, deli meats, or snacks.
- Potassium as a protector: Potassium is the balancing partner. It helps the kidneys get rid of excess sodium and also helps the blood vessel walls relax. You can find plenty of it in bananas, spinach, sweet potatoes, and avocados.
Exercise, in turn, is like a fitness workout for your blood vessels. Regular physical activity, especially endurance sports such as running, swimming, or cycling, makes the arteries more flexible and elastic. This means your heart has to pump less forcefully to send blood through the body, which can noticeably lower both systolic and diastolic blood pressure.
Stress and sleep as silent adversaries
Your mind and heart are an inseparable team. Stress - whether at work or in your personal life - puts your body on constant alert.
Stress hormones such as adrenaline and cortisol narrow your blood vessels and make your blood pressure shoot up in no time. If this becomes a constant state, it can develop into chronic high blood pressure.
The quality of your sleep is just as important. During sleep, your blood pressure and heart rate normally drop, giving your entire cardiovascular system a well-deserved break. Lack of sleep or restless nights disrupt this important recovery process and can raise your average blood pressure throughout the day.
When the Causes Run Deeper
Sometimes the factors that need adjusting aren’t just the obvious ones in your daily life. Your hormonal balance also has a say.
For example, an imbalance in thyroid hormones can disrupt your metabolism and, in turn, your blood pressure. Another important player is your cortisol level. A persistently elevated level, often a result of chronic stress, is considered a clear risk factor for high blood pressure. If you’d like to learn more about what cortisol is and how it affects your body, you’ll find more information here.
If you suspect that hidden imbalances may be playing a role, the nutrient and hormone tests from mybody®x (MYBODY Lab GmbH) can shed light on the situation. They help you better understand what’s going on in your body and take targeted steps to bring your blood pressure back into a healthy range.
How to Measure Your Blood Pressure Correctly at Home
Even the best reference values are no use if your measurement goes wrong. Measuring correctly at home is the foundation for making informed decisions about your health. Only with precise, regular checks can you build a data set that you and your doctor can truly trust.
The good news is that measuring correctly isn’t rocket science. There are a few simple but crucial rules that make the difference between an inaccurate snapshot and a truly meaningful result. Here’s how to make sure your readings reflect reality.
The Golden Rules of Self-Monitoring
To collect reliable data that you can use as a guide, you should keep a few basic things in mind. These will help you rule out the most common sources of error from the outset and get readings you can actually compare.
Simply follow this checklist every time you take a measurement:
- Relax: Before measuring, sit quietly for at least five minutes. Hurrying, stress, or physical exertion right beforehand can significantly distort the result.
- Use the right posture: Sit upright in a chair with both feet flat on the floor, and lean back comfortably. Important: Don’t cross your legs!
- Choose the right arm: It’s best to always measure on the same arm so the readings remain comparable. Rest your forearm comfortably on a tabletop so that the cuff is roughly at heart level.
- Stay quiet during the measurement: Talking or fidgeting can temporarily raise your blood pressure. Just sit still for the short duration of the measurement.
The time of day is also important. It’s best to measure at the same time every day, for example, in the morning right after you get up and before breakfast. This helps you establish a reliable routine and get comparable readings.
To make the process easier and help you avoid common mistakes, we’ve put together a short checklist for you.
Checklist for correct blood pressure measurement
This table summarizes the most important steps and most common mistakes to help you measure correctly at home and get accurate results.
| Step / factor | How to do it right | Common mistake |
|---|---|---|
| Preparation | Sit quietly and relax for at least 5 minutes. | Measuring right after climbing stairs or a stressful situation. |
| Posture | Sit upright in a chair, with your feet flat on the floor and your back supported. | Measuring with your legs crossed, while slouching, or standing. |
| Arm position | Rest your arm on a table at heart level without tensing it. | The arm is hanging unsupported or positioned too high or too low. |
| Cuff | The cuff fits and is positioned correctly on the bare upper arm. | Measuring over clothing or using a cuff that’s too loose or tight. |
| During the measurement | Stay quiet; don’t speak or move. | Talking, watching TV, or getting distracted. |
| Time | Measure at the same time every day, preferably in the morning and evening. | Irregular measurement times that make comparisons impossible. |
With these instructions in mind, your measurements will become more reliable each time.
What are the official values for home measurements?
It is important to know that the limits for self-measurements at home are slightly stricter than those used at the doctor’s office. Why? Because measurements in a familiar, relaxed setting are usually a little lower than when you’re slightly tense during a doctor’s visit—the famous “white coat effect.”
In Germany, according to the German Hypertension League, systolic readings between 120 and 129 mmHg and diastolic readings between 80 and 84 mmHg are considered normal for adults. Ideally, a reading is below 120/80 mmHg. Readings of 135/85 mmHg or higher when measuring at home are already considered high blood pressure. A blood pressure diary is invaluable for giving you and your doctor an overview of how your readings change over time.
By following these simple rules, you take an active role in managing an important health marker. You collect valuable data that helps you better understand your body. If you’d like to look deeper and identify connections between your lifestyle and important bodily responses, our at-home self-tests offer an excellent way to check other health markers.
What can you do yourself to maintain healthy blood pressure?
Measure your blood pressure regularly, as the German Hypertension League recommends, especially from the age of 40 (German Hypertension League, accessed 2026), and put the lifestyle tips from the previous chapters into practice in your daily life.
Now you have everything you need to understand what makes for healthy blood pressure and what you can do to improve it yourself. Stable blood pressure is a foundation for an active life. Your most important tools? Regular measurements and a mindful lifestyle.

Your most frequently asked questions about blood pressure
To wrap up, we’d like to answer a few questions we hear again and again. We hope this information gives you even more confidence in managing your blood pressure readings and helps you better understand your body’s signals.
Is low blood pressure dangerous?
Low blood pressure, medically known as hypotension, usually means readings below 100/60 mmHg. The good news: In most cases, it’s completely harmless. Sometimes, it may even put less strain on your cardiovascular system.
Of course, symptoms such as dizziness or fatigue can be quite bothersome, but they are rarely a cause for concern. As long as you feel okay, you generally don’t need to do anything. Only if the symptoms noticeably interfere with your daily life should you talk to your doctor to make sure nothing else is causing them.
How quickly can I lower my blood pressure?
A healthy and, above all, lasting reduction in blood pressure is a marathon, not a sprint. If you focus on a healthier lifestyle with a balanced diet and more exercise, it often takes several weeks to months to see lasting results. Patience is key.
For now, targeted relaxation exercises such as deep breathing can bring your readings down a little in the short term. If you take medication, the effects usually appear within a few days. But remember: what matters is long-term consistency, not a quick result for one day.
How does coffee affect blood pressure?
Yes, the caffeine in coffee can actually temporarily raise your blood pressure. This is especially noticeable for people who only drink coffee occasionally. The effect then lasts for about two to three hours.
But if you drink coffee regularly, your body gets used to it. Experts call this tolerance development. The increase is then often much smaller or may not happen at all. Still, never measure your blood pressure right after a cup of coffee, so you don’t skew the results.
Why is my blood pressure higher in the morning than in the evening?
A slight increase in the morning is a completely normal biological rhythm. After all, your body wants to wake you up and get you ready for the day. To do this, it releases hormones such as cortisol, which rev up your whole system - and your blood pressure along with it.
This mechanism is harmless for most people. However, if the increase in the morning is extremely pronounced - known as the “morning surge” - the risk of cardiovascular problems may be higher. In that case, it’s a good idea to get it checked by a doctor to be on the safe side.
